'IMPROVED PUNCHING- AND SHEARING-MACHINE.

The Schedule referred to in these Letters Patent and making part of thename.

To all whom it may concern:

Be it known that we, WILLIAM H; IVENS and WiLLiAM F. BROOKE, bath ofTrenton, `in Mercer county, and State of New Jersey, have inventedcertain new and useful Improvements in Punching and Shearing-Machines,and we do hereby declare that the following is a full, clear, and exactdescription tl1ereot`,'refereuce being had to the accompanying drawing,forming part of this specilication, and in which-- Figure 1 representsacentral longitudinal section of a machine embracing our improvements.

Figure 2 is a transverse section of the same, taken on the line. x x oflig. 1.

Figure 3 is an end view of the punching or shearing-head, with thetaceplate removed, to show its operati:lg-mechanism. f

The same letters indicate like parts in all the tigures.

lhe object of this invention is to produce a machine possessing greatpower, combined with simplicity and eheapness ot' construction; and

1t consists in a novel arrangement and combination of mechanical devicesto accomplish the desired end.

To enable others to more clearly understand the construction andoperation of our machine, we describe it by referring to the drawing, inwhich-7 A represents a lsolid casting, constituting the frame of themachine, and so formed as to. furnish an anvil, cl., and punch or shear,carrying jaws b at each side, through which latter are passed,longitudinally of the machine, the two shafts B, which meet in a pillar.block, C, in the centre.

On each of these shafts B is firmly keyed an el1ipable motor.

The punching or shearing-heads J have 'a transverse slot, c, 3, in whichthe box e has a sliding mot-ion communieatml by the eccentric wrist d,and through the rotation of the shaft B, and said wrist, a vertieailreciprocating motion is given tothe punching or shearing-head.

'.lhe'eccentric gears'l) are so arranged en the shafts B, with relationto the wrists d, that the .greatest amount of leverage is appliedwhile-the dies or shears arepassing through the metal to be punched orcut., and the upper gears, being arranged opposite to each other on theshaft G, will cause the one head to descend, while the other is rising,alternately.

rlhese heads and auvils may beprovided with punches, shears, and dies,as described in Lette-1s Patent No. 94,117, granted to us, August 24,1865).

What is here claimed as new, and desired to be secured by Let-tersPatent, is

The combination of the shafts B, having eccentric wrists d, slidingboxes c, with the heads J, eccentric gears D E, and driving-shaft G,substantially as set fort-h.
